A hottie Bravest who moonlights as a raunchy nude stripper has been tossed on desk duty after being busted for steroid possession, authorities said yesterday.

Rodney St. Cloud, Mr. April in the Fire Department’s official 2004 calendar, was taken off the line at Engine Co. 43/Ladder Co. 59 in The Bronx and put on administrative duty after his arrest May 23, sources said.

But while higher-ups appear to have considered St. Cloud literally a poster boy for the department in the past, they may want to rethink their position.

The two-year fireman – who recently placed 12th in the 2003 Mr. Olympia competition and is known as “Hot Rod” in the exotic-dancing world – was found with “a large shipment of steroids,” one source told The Post. “But the grand jury was dismissed because they couldn’t prove intent to sell.”

Sources said St. Cloud, 30, tested positive for “controlled substances” after his arrest, but did not elaborate.

FDNY spokesman Frank Gribbon only said the department has a “zero tolerance” policy regarding drug use. “There are administrative charges pending” against St. Cloud, he added.

St. Cloud’s act even got too hot for the sexy male dance group where he worked for four years.

Tony Abrahms of Nyc HotBoyz said he booted the Bravest because he was too sexually explicit. “He goes totally nude, and we don’t do that,” Abrahms said.
